To allfwla-omitmay concern:

Be it known that we, dance D. /Vnirn and Urns. S. Sron'i, citizens ofthe United States, residing at Nallen, in the county of Fayette andState of West Virginia, have jointly invented certainnew and usefullmprovements in a Stearnlflngine, of which the followingis aspecification' This invention relates to steam engines and moreparticularly] to those especially adaptedfor use in connection with1000- motives of the geared type, the primary object of the inventionbeing to'provide an improved steam engine and gear mechanism which willresult in greater efficiency, particularly when thelocomotive is goingup and down grades or moving around short curves. 1

/Vith the above and other objects in view, as will appear thedescription proceeds, the invention comprises the various novel featuresof construction and arrangement of parts which will be more fullydescribed herein and set forth with. particularity in 25 the claimsappended hereto.

Reference is had to the accompanying drawings forming a part of thisapplication, in which like reference characters indicate thecorresponding parts throughout the several views, in whicl1-- Figure lis an end elevation partly in section, of the improved steam engine.

, Fig. 2 is a plan viewthereof.

Fig. 3 is a longitudinal section 011 a reduced scale of the improvedapparatus.

Fig. 4 is a transverse section on the line it-A of Fig. 3.

Fig. 5 is a sectional detail of a part of the supporting body or frame.

Fig. 6 is a perspective View of the supporting platform and itsattachments.

The improved engine is designed more particularly for use in connectionwith the class of geared locomotives used in large manufactories wherespecial railway tracks are employed for carrying material from place toplace, and in which short and sharp curves or grades are encountered.These locomotives are usually equipped with twin cylinders operating ona single crank shaft supported longitudinally of the boiler and frame,and coupled to the driving axles of the track wheels by suitablegearing, and thus called geared locomotives.

The present invention is for certain improvements on this class oflocomotives, and

Serial No. 534:3,5d9.

comprises a crank casing" or support including a platform orupperhorizontal portion 13 and plurality of outer vertical webs l3 andan ...itermedia te vertical web 17. The platform and. websareincoactingsections engaging at their platform sections having upwardlydirected flanges l l connected'by bolts '15, andthe outer webs supportedby clamp plates 13 withbolts or shown at 16, The supports 18 and 17 thusproduce the supporting structure and crank case 'in which the crankshaft is journaled.

'lhe outer edges of the webs l3 and 1? are inclined inwardly anddownwardly and terminate in shaft bearings 18, eaclfbearing having abushing or the like 23 to re ceive the crank shaft, which is formed inthree sections, an intermediate section '22 supported in the bearing ofthe intermediate web 1?, and outer sections 21 supported in the bearingsof the outer webs l3.

The conifronting terminals of the shaft sections are provided .withcrank or face plates 2-1 being thus arranged in pairs, and each. paircoupled by a wrist pin to re spcctively receive the straps 25 ofconnecting rods 27 of the engines.

The wrist 1' trically opposite sides of the pairs of face plates, sothat the engines will be prevented from stopping on the center, as willbe obvious.

The bearings for the crank shaft sections include suitable holding capsas shown at 20.

The cylinders are represented at 30 and are arranged in divergentrelation as shown. Each cylinder is provided with an extension 59 havingopenings to form guides for the cross heads 28.

Each extension 59 is formed with a pro jection 28 extending beneath theadjacent edge of the platform 13, and coacting with an angular straporbracket 5'? attached to the extension 59 and to the platform, asshown. By this means the cylinders, tl'ie extension and the platform arefirmly united and held from displacement under the severe strains towhich they are subjected when in use.

The coupled cylinders and the crank shaft confronting edges, the,

other fastening devices as sins are arranged atdiamesupport, are mountedupon a suitable bed 7 relation depending from the platform members andengagingedge to edge and with bearings for the crank shaft at theirlower ends, clamp members connected to the outer webs to bind thesections together, ribs extending upwardly from said platform membersand engaging face to face, fastening devices operating through saidribs, cylinders in diverging relation, and cross head guides betweensaid cylinders and supporting sections and connected thereto.

2. In a motor, a crank shaft support com prising a platform and aplurality of supporting webs depending from the platform in spacedrelation and having crank shaft bearings at their ends, cylinders indiverging relation to said support, and cross heads guides between saidcylinders and support, each cross head guide being provided with aprojection bearing beneath the supporting webs, and angular clamp platesconnecting the cross head guides to the platform members at pointsopposite to the projection.

In testimony whereof, we affix our signa tures hereto.
